AIM: To explore the surgical methods and clinical effects on young patients with congenital lower eyelid entropion.
METHODS: There were 27 patients ( 45 cases ) who suffered congenital lower eyelid entropion accepted the modified blepharosphincterectomy. The clinical effects and complications were evaluated.
RESULTS: After followed up for 6mo, 42 eyes were fully recovered, 3 eyes were unsuccessful and the cure rate was 93%, 5 eyes suffered minor lower eyelid skin folds, none had lower eyelid retraction and ectropion.CONCLUSION: Modified blepharosphincterectomy is an ideal cosmetic surgical treatment for young patients with congenital lower eyelid entropion. It is an effective surgical treatment with fewer complications.

0.05).Conclusion: The method of constructing a highly invasive subline of bladder neoplasm is reliable,and EGFP transfection does not change the biological behavior of the cells.The obtained sublines may provide a valuable experimental platform for further study on the molecular mechanisms of bladder neoplasm metastasis.

Methylotrophy is a kind of widespread microbe which can use carbon compound as their only carbon and energy sources.It has been reported that methylotrophy can directly use one carbon com-pound to transform into their own metabolic one carbon unit,then these one metabolic one carbon units can be used as energy and carbon skeleton by organisms,which is a main part in one carbon metabolism.Because this is a novel metabolic system,it can be used in the study of biological metabolism and evo-lution.Based on the previous study about Methylobacterium sp.MB200 in our lab,here we summarized the research improvements about methylotrophy from their taxonomy,metabolism,genomics and ap-plications.

Objective To investigate the current status of multidrug-resistant organism (MDRO) infection in the general surgery department of a tertiary first-class hospital, and understand the efficacy of comprehensive intervention measures.Methods Targeted monitoring on MDROs was implemented among patients who were hospitalized in a general surgery department for>48 hours between March 2015 and October 2016, comprehensive intervention measures were taken since January 2016.MDRO infection before and after intervention was compared.Results Between March 2015 and October 2016, a total of 6 406 hospitalized patients were monitored, 155(2.42%) developed MDRO infection.The most common infection sites were abdominal cavity(hydrops, bile) (n=76, 49.03%) and surgical site (n=43, 27.74%).MDRO infection rate dropped from 2.79% (99/3 549) before intervention (March-December, 2015) to 1.96% (56/2 857) after intervention (January-October, 2016) (x2=4.612, P=0.032).There was no difference in MDROs between before and after intervention, the major were both Escherichia coli.Conclusion Comprehensive intervention measures can reduce the incidence of MDRO infection in the general surgery department of this hospital.

To improve the efficiency of medical research resource distribution in Beijing,based on the analysis of the existing problems we discussed the new model of resource integration.The model includes establishing all information-sharing platform and two operation modes of research project.By using this model it would be assured to achieve the best allocation efficiency and maximizing profits for Beijing medical research resources.

Objective To investigate the role of local aldosterone system in oncofetal fibronectin ( oncofetal FN) mRNA expression and reactive oxygen species (ROS) production in human mesangial cells (HMCs) exposed to short-term intermittent high glucose and the effect of Fenofibrate.Methods The HMCs were divided into 8 groups:normal glucose(NG) ;osmotic fluctuation(OF) ;mean glucose load (MGL) ;stable high glucose (SHG),short-term intermittent high glucose (IHG) ; intermittent high glucose plus eplerenone (IHGE) ; intermittent high glucose plus fenofibrate(IHGF) ; and normal glucose plus fenofibrate (NGF) groups.The mRNA expression levels of Aldosterone synthase ( CYP11 B2 ),11 β-hydroxysteroid dehydrogenase type 2 ( 11βHSD2 ) and oncofetal FN were determined by RT-PCR.The expression of CYP11B2 protein was determined by western-blot.Aldosterone level in cell culture supernatant was detected by radioimmunoassay.The expression and translocation of mineralocorticoid receptor (MR)protein were assayed with confocal laser scanning microscopy. ROS levels were determined by Fluorescence microscopy and fluorescence microplate reader.Results ( 1 ) MGL,SHG,and IHG groups showed a 2.41,3.63,and 4.45 times increase in CYP11B2 mRNA expression,and a 1.83,2.15,and 2.78 times increase in CYP11B2 protein expression,respectively,compared with NG group (P ＜ 0.05 ).The aldosterone levels of HMCs culture supernatant in MGL,SHG,and IHG groups were also increased,being 1.49,2.04,and 2.54 times of that in NG group ( P＜0.05 ),and the degree of elevation in IHG group was more marked than that in SHG group( P＜0.05 ).MR was activated and translocated from cytosol to nucleus in MGL,SHG,and IHG groups.Quantitative analysis showed the ratioes of cytosol/nucleus fluorescence intensity in MGL,SHG,and IHG groups were 15％,38％,and 53％ decreased as compared with that in NG group,and the decrease was more marked in IHG group ( P＜0.05 ).(2) Oncofetal FN mRNA expression and ROS levels in MGL,SHG,and IHG groups were increased,being 1.54,2.31,3.65 and 1.26,1.91,2.48 times of those in NG group,respectively ( P＜0.05 ),and this increase was more marked in group IHG ( P＜O.05 ).Compared with IHG group,oncofetal FN mRNA expression and ROS levels in group IHGE were significantly decreased by 54％ and 53％,and in group IHGF by 45％ and 39％. ( 3 ) CYP11B2 mRNA,protein,and aldosterone levels in IHGF group were decreased by 74％,59％,and 50％,and the activation of MR in group IHGF was inhibited when the ratio of cytosol/nuclear fluorescence intensity was increased 1.88 fold as compared with that in group IHG ( P＜0.05 ).Conclusions Increased expressions of oncofetal FN and ROS by HMCs induced by short-term intermittent high glucose were nore marked than those induced by stable high glucose.The mechanism was associated with activation of local aldosterone system.Fenofibrate may inhibit the activation of local aldosterone system and alleviate the injury to HMCs induced by intermittent high glucose.

Salvia miltorrhiza Bge. is a perennial deciduous flowering plant. Its medicinal root and rhizomes part is widely used in the treatment of various diseases. In this study, bioinformatics analysis was performed to identify 4832 genome SSR loci with length longer than or equal to 40 bp from the draft genome assembly of S. miltorrhiza. The re-sults showed that the dinucleotide repeat motifs and trinucleotide repeat motifs constitute the main types of genome SSR loci, accounting for 37.3% and 61.3% respectively. SSR types enriched with A/T bases showed significantly higher abundance than other types, including AT/TA AAT/ATT, ATA/TAT, TAA/TTA, accounting for 30.5%, 21.6%, 17.1%, 20.4% of the total number of SSR loci, respectively. 1079 primer pairs were designed for these genome SSR loci. These primers can be used for genomic diversity analysis, genetic map construction, genetic marker screening. These data could lay the foundation for population genetics and genomics research of S. miltorrhiza.
